In Packaging?: Yes

Clean air fans exhaust odorous, hot, or stale air. These fans use a propeller that's directly mounted on the motor shaft. This reduces friction and improves efficiency compared to a belt-drive fan. Direct-drive fans have fewer moving parts and typically require less maintenance than belt-drive fans.
